In univariate analyses, older age, obesity, hypoalbuminemia, elevated CRP, phosphate above target, vascular comorbidities (peripheral and cerebrovascular disease), diabetes, low dialysis dose (eKt/V < 1.2), and lower ultrafiltration were all significantly associated with mortality, whereas patients with preserved LVEF had a better survival (Table 2). Here, CRP is linked to obesity due to melanocortin 4 receptor deficiency.
